In the Official World Golf Ranking, as in popular perception, nothing is more important than winning majors. Thus, the agreed-upon standard for determining who the best golfer in the world is involves assigning the most ranking points to a major victory.
It's no surprise, then, that those at the top of the OWGR at present have tasted victory in golf's most significant tournaments, with all other tournaments taking a back seat. Even the next tier beneath majors (FedEx Cup events, the Players Championship, etc.) don't earn golfers nearly as much ranking capital.
It's impossible to predict the future, and the Official World Golf Ranking rarely seems to make perfect sense (owing largely to the shortness of our memories). With this said, let's take a look at one projection for who will occupy the top 10 slots in the OWGR in five years' time.
